(Nutr Diet 2005;62:123–129)Objective: To determine the characteristics of adult New Zealand (NZ) supplement users. Design: Secondary data analysis of a cross‐sectional national survey. Subjects: A total of 4636 adults aged 15 years and above. Setting: Homes throughout NZ. Methods: The National Nutrition Survey (NNS97), linked to the NZ Health Survey, had a multistage sampling design providing a representative sample of the NZ population aged 15 years and above. Secondary data analysis using logistic regression was used to determine characteristics of dietary supplement users (n = 2749) by a range of demographic, lifestyle and dietary variables. Results: Income, marital status, Index of Deprivation (NZDep96 quartile) and place of residence were not independently associated with dietary supplement use. The odds of consuming dietary supplements over the previous year was increased in younger adults. Participants in the ‘NZ European and others’ ethnic group were the most likely to be supplement consumers compared with Māori and Pacific participants. Dietary intakes from food, for folate, riboflavin (males), vitamin C (females), niacin (females), dietary fibre (females) and calcium (males) were significantly higher in supplement users. Conclusions: NZ supplement users are characteristically female, of ‘NZ European and others’ descent, well educated and relatively young. Nutrient intake from foods and beverages alone was adequate for those individuals who chose to include supplements in their diet.
